IMPROVEMENT IN GANG-PLOWS.

Specification forming part of Letters Patent No. 155,871, dated October 13, 1874 application'filed August 17, 1874.

To all whom it may concern:

Be it known that we, ROBERT N. Howns, WILLIAM A. Done, and JOSHUA B. WEBSTER, of Stockton, San J oaquin county, State of California, have invented an Improved Gang- Plow; and we do hereby declare the following description and accompanying drawings are suflicient to enable any person skilled in the art or science to which it most nearly appertains to make and use our said invention or improvement without further invention or experiment.

Our invention relates to improvements in that class of gang-plows in which a series of two or more plows are secured to a diagonal timber, which timber forms a part of the plowframe. In order to describe our improvements reference is had to the accompanying drawings, forming a part of this specification, in which- V Figure l is a perspective view of our plow. Fig. 2 is a view of the caster-wheel and its fastening. Fig. 3 is a view of one plow. Fig. 4 is a view of one attaching-plate.

A is the diagonal timber which carries the plow, and B G D are three parallel beams, the rear ends of which are secured to the diagonal timber A. These timbers extend forward and are connected together by the transverse beam E at theirforward ends. To the diagonal timber A I secure as many plows F as the length of the timber will accommodate. Each plowstandard is cut with two arms, 9 g, and a horizontal flange, h, is formed upon or secured to the upper ends of the arms. The arm g of the standard is composed of two upright leaves or plates which meet along one edge so as to form a V-groove behind them. The lower end of one of these plates is secured to the reverse side of the mold-board I, near its middle, while the opposite plate extends down andis attached to the land-side. Across-bar, 03, connects these two plates opposite the middle of the mold-board, as shown. To secure the plows to the timber the horizontal flange h is screwed, bolted, or otherwise secured against the under side of the timber, and a long bolt or rod, j, the lower end of which is secured in the crossbar 17, passes up along the groove behind the two plates and through the timher, so that a nut, I, can be screwed down upon its upper end above the timber, and thus bind the standard firmly in place. Thus the plows are made easily removable in case they should need repairs, while a strong, substantial standard is provided. In order to provide a draft attachment I employ a bar, M,

the opposite ends q of which are bent upward. These upward-bent ends fit in the proper grooves or slides on the inner sides of the beams B G and at their forward ends, so that the bar connects the forward ends of the beams. These bent ends can be moved up or down, as desired, in their guides r, and se cured at the desired point bya screw moving in a slot, 0, in the bent ends or otherwise, so as to regulate the height of the draft. A

brace-rod, 12, has one end attached by a bolt or screw to each timberB 0 back of the draftbar, and extends down to the angle or bend of the draft-bar, to which it is again bolted or screwed, and thus serves as a brace for the bar. Holes 8 s s are made in the draft-bar, in either of which the clevis I can be attached, as desired. The frame is mounted on casterwheels, which can be adjusted up or down, so as to raise or lower the plows, while ahandle, V, at the rear end of the frame, serves as a means of cnablin g the driver to ship the frame. The caster-wheel u is secured to the lower end of both a vertical bar, X, and an angular or bracing-bar, p. The bar 12 moves in a slide on the side of the timber B of the plow-frame, so that the wheel can be raised or lowered by moving the bar 1; up ordown. A rod, W, has one end secured to the draft-bar M, thus providin g a brace which will prevent any shifting of the draft-bar. The caster-wheelu, which supports the opposite front corner of the plowframe, is secured to the bent lower end of a standard, X, that supports it upon one side only. A plate, 3 is secured to the opposite side of the standard and thence down to the journal of the wheel, which passes through it. It is then bent to one side and its extremity is formed into a scraper, 3 which will keep the tread of the wheel clear. This side plate may be used or not, as desired, according to the character of the soil in which the plow is working, as it is desirable, where the soil is PATENT OFFICE.

light and dry, to have only one sidesupport for the caster-wheel; but where the soil is heavy and wet the side plate will be used, as the scraper will keep the fork from clogging. By this arrangement We provide a simple and convenient draft attachment for the plows, which be readily adjusted in height, so as to throw the point of the plow up or down, as desired, while, by shifting the clevis I toward either end of the bar M, the plows can be turned to or from the land, to regulate the Width of furrow.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-
